<h3><u>Required </u><u>Answer</u><u>:</u></h3>

The substance in reactants side shows a alkane which is burnt. As a result of combustion, Carbon dioxide and water is formed.

The equation will be like this:

\rm{ C_8H_18 +  \dfrac{25}{2}  O_2 =8 CO_2 + 9 H_2O }

Now here we can see that the stoichiometric coefficient is a fraction, hence Multiplying 2 in both sides of the eq.

\rm{2 C_8H_18 + 25 O_2 = 16 CO_2 + 18 H_2O }

Convert 7.50 grams of glucose C6H12O6 to moles
Lera25 [3.4K]

Answer:

The number of mole is 0.04167mole

Explanation:

To convert gram to mole, we need to calculate the molecular weight of the compound

C6H12O6

C - 12

H - 1

O - 16

Molecular weight = 6 * 12 + 1 *12 + 6 * 16

= 72 + 12 + 96

= 180g/mol

To covert gram to mole

Therefore,

= 7.50g/ 180g/mol

= 0.04167 mole of glucose

Which of the following pieces of laboratory glassware should be used to most accurately measure out a 25.00 ml sample of a solut
wel

Answer:

The correct answer is 25 mL graduated cylinder (it should be used in all the cases)

Explanation:

In order to measure 25.00 ml sample of a solution it should be used a 25 mL graduated cylinder, as it is previously and properly calibrated. The other laboratory glassware, beaker and erlenmeyer, have graduations which are approximate, so they are used when exact volumes are not needed.

ii) graduated cylinder has the least uncertainly. It is more accurate than a beaker or erlenmeyer (to within 1%)

iii) A 25 mL graduated cylinder should be used because it is the most accurate lab glassware (between those were mentioned: beaker, erlenmeyer).
